Exchange Online Transport Rule to Encrypt Sensitive Email

Microsoft has released details of an Exchange Online transport rule to encrypt outbound email containing sensitive data types like credit card numbers. The rule works (after fixing the PowerShell), but needs to be reviewed and possibly adjusted to meet the needs of Office 365 tenants.

Applying Autosignatures with Transport Rules

Office 365 tenants can use Exchange transport rules to apply autosignatures to outbound email, including messages protected with encryption. You can even include some properties of the sender extracted from Azure Active Directory, and you can add an exception so that the autosignature isn’t applied to replies.

Sending Protected Email to Teams, Yammer, Groups, and Shared Mailboxes

Encrypted email is becoming more common within Office 365. Things usually flow smoothly when sending protected messages to email recipients, but other Office 365 recipient types like Teams and Yammer might not be able to handle protected email.

Searching for Encrypted Office 365 Information

Making it easy to protect Office 365 content with encryption is great, but it has some downsides too. One of the obvious problems that we have is that encrypted documents in SharePoint and OneDrive for Business libraries can’t be found unless their metadata holds the search phrase.

Protected PDFs Now Generally Available with Azure Information Protection

The Microsoft-Adobe initiative to support Azure Information Protection for PDF files has reached general availability. Things look good and the issues encountered in the preview are removed. You can store protected PDFs inside Office 365, but be prepared to download the files to be able to view them.
